Abstract

Industry is demanding ever-greater volumes ofwater, while at the same time producing wastes and effluents,which in many places taint and damage the quality of thisprecious resource on which all life depends. The water balanceof industrial parks is not well known. This article formalizes asystematic water mass balance framework to quantify waterflows into, water flows inside and effluents out of the industrialpark. Using the method, Long Thanh industrial park in DongNai province, Vietnam was evaluated. The approach makesvisible large flows of water that have previously beenunaccounted and ignored. In 2012-2014, the industrial parksvaried 28 to 53% for water consumption for production, 40 to45% for effluent discharge. The approach demonstrates how theprinciples of water balance can help robust water accounting,monitoring, optimum operating and management in industrialpark.
